x+2y = 7,2+54=4​

Answer 1

Answer:

equation 1 = x+2y=7

equation 2 = 2x +54y =4

multiplying 2 in equation 1

2(x+2y=7)

2x+4y=14

So , equation 3 = 2x+4y=14

equation 3- equation 2

2x+4y=14-2x-54y=-4

-50y=-10

50y=10

y=10/50

y=1/5

Step-by-step explanation:

put vale of y in equation 1

now , x+2y=7

x+2×1/5=7

x+2/5=7

5x+2/5=7

5x+2=7×5

5x+2=35

5x=35-2

5x=33

x=33/5

So, the value of X = 33/5.

and, the value of Y = 1/5.
